Founding - Ultrasonic examination - Part 3: Spheroidal graphite cast iron castings

This part of this standard specifies the requirements for the ultrasonic testing of steel castings for turbine components (with limited content of austenite) and the methods for determining internal discontinuities by the pulse echo technique. This part of this standard applies to the ultrasonic testing of steel castings which have usually received a grain refining treatment, and with wall thicknesses up to and including 600 mm.

The frequency value shall be selected to suitthe examination and shall be within the range 0,5 MHz to 5 MHz. Higher frequencies can be used for examin-ing wall thicknesses of less than 20 mm or areas close to the surface.NOTE 2For the detection of near-surface discontinuities, the use of twin-crystal and/or angle probes is recommended.NOTE 3Since sound travels at different velocities in steel and spheroidal graphite cast iron, the actual angle of refractiondeviates from the nominal angle of the probe for steel.If the sound velocity of spheroidal graphite cast iron is known, the angle of refraction of the probe can be deter-mined from the sound velocity according to Figure 2.Figure 3 shows how the angle of refraction can be determined to an accuracy sufficient for practical purposes usingtwo probes of the same type. The sound velocity of spheroidal graphite cast iron can also be determined from theangle of refraction a as follows:sccaasinsin2553´=C(1)SIST EN 12680-3:2003
